Abstract

In a system having a bi-directional auxiliary channel arranged to transfer information between a video source and a video display and vice versa and a unidirectional main link arranged to carry a number multimedia data packets from the video source to the video display, a method of establishing a stable main link. The method is carried out by performing a link training session carried out over the auxiliary channel to establish the stable main link, prior to starting transmission of multimedia data packet streams from a video transmitter to a video receiver over the main channel.
